Google founders Larry Page and Sergey Brin are the latest to take the 'Ice Bucket Challenge,' the fundraising effort that has now raised more than $13 million for ALS (amyotrophic lateral sclerosis) research, after they were challenged last week by Microsoft CEO, Satya Nadella.

Since the challenge started going viral on social media, other tech CEOs have taken it too, including Elon Musk, Tim Cook and Jeff Bezos. Bill Gates had the best video so far, but the Google founders did a good job too.

The duo called upon a couple of "Nooglers"- what Google calls its new employees - to do the bucket-dumping honour. Tons of Nooglers attended to watch the show.

Page reacted by saying that it was "quite refreshing," while Brin claims that it was "worse than expected, honestly". However, they didn't heed tradition and nominate someone else to take the challenge.
